"UNITED STATES 1 PATENT ROBERT ELLSWORTH DANIELS, OF YOUNGSTOWN, OHIO,A ASSIGN OR OF ONE-HALF TO I-IOSEA HUFFSTOT, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 603,813, dated May 10, 1898.

Application led July 26, 1897.

To all whom, it may concern:

Be it known that I, ROBERT ELLswoRTH DANIELS, a citizen of the United States, .residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in YMachines for Shearing and Bending Metal, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to machines for bending and shearing metal, and is designed by certain mechanical constructions and arrangements of its parts to automatically form and cut ready for the market a peculiar form of metallic fabric commonly known as corner-shield and used in the construction of y buildings to form the edge of rentrant corners and to receive the Aplastering and prevent the breaking away of the same, all as now Well known to the builders art.

In fully describing my invention I will use A the accompanying drawings to illustrate the details thereof, and in which- Figure 1 is a front elevation of my machine as itappears to the eye. Fig. 2 is a plan view thereof with covering-plates removed. Fig. 3 is a transverse section thereof on the line 3 3. Fig. 4 is a vertical section upon the line 4 4. Fig. 5 is avertical section upon the line 5 5. Fig. 6 is a section upon the line 6 6 of Fig. 5. Fig. 7 is a segregated perspective of the shearing and bending dies; and Figs. 8 and 9 show the metal strip as it enters and leaves the machine, respectively.

In the several views the same numeral valways indicates the same part.

l is the table or bed of the machine, supported by the legs 2, having the structural webs 3, having the bosses 4, containing the bearings 5, in which are journaled the rocking shafts 6, to which are keyed the bellcranks 7, comprising the trip-levers 8, reaching to the central portion of the machine, and the levers 9, ending in the ball-head 10.

Depending from the mid-portion of the table or bed 1 arethe hangers 11, having bearings 12, in which is j ournaled the power-shaft 13, receiving power from some convenient source, and keyed to which are the parallel Serial No. 645,878. (No model.)

cams 14, each impinging the end of one of the trip-levers 8.

From the mid-portion of the bed 1 there projects forward or to the front the brackets 15 and 1G. The bracket 15 has the vertical slot 17, in which is keyed the slidable boxing 18, in which is journaled the stud-shaft 19 of the horizontal feed-wheel 20. A 4coil-spring 2l projects the boxing 18 in its seat toward the bracket 16, in the bearing 22 of which is journaled the stud-shaft 23 of the horizontal feed-wheel 24, impinged by the wheel 20. At the lower end of the shaft 23 is keyed a ratchet-wheel 25, engaged by the pawl 26, pivoted in the box 27, having iianges 28, slidably keyedin the' railslots 29 under the bracketdl. Within the box 27 is a spring 30, adapted to press the pawl into engagement. Journaled to the Wrist-pin 31 of the box 27 is a pitman 32, pivotally secured to the slot 33 of the crank-arm 34, keyed to the rocking shaft 6.

Adjacent to the respective ends of the bed 1 are disposed slots 35, through which project the lugs 36 of the die-carriages 37, the said lugs containing the sockets 38, in which engage the' heads 10 of the lever 9, forming a universal joint. The carriage 37 is provided with the flanges 39, sliding back and forth in the ways 40, made by the guide-blocks 41, secured to the bed 1. In the channel 42 of the carriages 37 are secured the hammer-block 43 and the bevel-faced die 44 by the yoke 45, secured to the carriage. the mid portion'of the machine, where it meets a bevel former-block 46, secured in the box 47 by the yoke 48 and adapted to be adjusted by the screws 49. The dies 44 are so disposed by means of certain packings 50 within the boX 47 and set-screws 51 that during the stroke of the machine they will pass sufficiently near each other to shear the strip 52 of material fed thereto by the feed-rolls 2O and 24 at the point 53, while the further movement of the said dies will bend the metal down upon the former-block 46 into the wings shown at 54.

The die 44 extends to Beneath the die 44 is a S101; 55 in the bed 1 l IOO clamping-bar 57 and which contains the coilspring 5S, controlling the same. The bar 57 is of such length and is so adapted to slide upon the bed of the machine that the ham'- mer-block 43 will strike it at the proper point in the traverse of the die 44 and that the said bar 57 will clamp the portion 59 of the metallic strip against the vertical face of theformerblock 43 to aid in the bending of the wing 54.

Extending lbelow the table l are the lugs 60, with lateral studs 6l, bearing stiff coil-springs 62, also guided by the lateral studs 63 of the lugs 36 of the carriages 37, by means of which spring the said carriages are returned ready for the succeeding movement of the lever 8. The spring 5S will operate the clamp-bar in a similar manner, thus releasing the metal strip 52 sufficiently to permit the feed of the feedwheels 2O and 24 of such diameter that the movement of the pawl, alreadyindicated, will feed suiiicient material to make room for a new cutting and forming.

Adjustment of the former-block 46 is made by the set-screws 49 and of the shearing movement by the set-screws 51. The set-screws 64 and 65 adjust the movement of the hammer 43 and the die 44, While a further adjustment of the feed movement is obtained by means of the setting of the slot 33.

Having fully described my invention and indicated its operation, the latter need only be brieiiy described, as follows: The metal strip 52, as shown in Fig. 8, is fed intermittently into the machine by the feed-wheels, each intermittent thrust being regulated according to the width of the completed work. The strip being in the machine, the dies 44 and the clamping-bars 57 pass each other and, shearing the metal, form it into wings against the former-blocks46. The reverse movement of these parts taking place a new section of the material is fed into position for the new stroke.

Having fully described my invention, what I desire to secure by my Letters Patent and to claim isl. In a machine for shearing and bending metal as described, the former-blocks, the'V dies and clamps, means for actuating the said dies and clamps intermittently, and means for feeding the material between the said dies and clamps and said former-blocks intermittently, substantially as and in the manner described.
